“No,” Cherry said slowly… “not innocent. You’ve seen too much to be innocent. Just not… dirty.”
I love this quote from Cherry because it really summarizes Pony and Johnny in a way I feel the fandom sometimes struggles with. She's directly saying that yes, they've seen shit. They aren't innocent or sugary sweet, and she can tell just by looking at them that they are hardened in some way that has made a visible impact on them. But also, their pain doesn't cover them like dirt - it isn't drying on their skin and staining their clothes and drawing everyone's eye. It isn't a permanent, skin-deep pain that has hardened their exterior and tainted their interior.
Of course, it's just a summarization of what she sees. A general statement. There's nuance lost in it, the way nuance is lost in most summaries. Still, it accurately reflects Johnny and Pony's characters. While the fandom often looks at Pony and Johnny and sees characters who are soft, anxious, twitchy, shy, and helpless, Cherry sees them for who they are. They aren't soft, they just don't see a point in needless violence. They're not anxious and twitchy, they're on guard and tense. They aren't quiet because they're shy, they're quiet because they're thoughtful. Introspective. Observant. They aren't helpless, they're just constantly faced against people and environmental/physical factors that anyone would struggle against, and they still manage to power through.
It also feels important to note that S.E Hinton does this everywhere - adding in 'small' details and quotes that actually really add to either the characters, foreshadowing, main themes and ideas, or plot.
